Abstract (en)
[origin: EP3421009A1] An aortic bare stent (100) and an aortic dissection stent are disclosed. The aortic bare stent (100) is in a tubular net structure, with multiple support stents (110) in circles and arranged along an axial direction. Two adjacent support stents (110) are connected by a connector stent (120). The connector stent (120) is made of a hyper-elastic material. A flexural rigidity of the connector stent (120) is less than that of the support stent (110). The support stent (110) is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent (120) is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material. The aortic bare stent (100) has a proper radial support strength, a proper axial support strength, and a good bending flexibility, and when being released, the aortic bare stent is easy to be bent to be adapted to the form of a blood vessel, thereby reducing the compression to a blood vessel wall.
